Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an improvement in an excrement processing device that automatically separates and processes excrement from livestock such as pigs kept in a livestock shed.

"Prior Art and its Problems" Various excrement separation and treatment devices have been proposed for the hygiene management of livestock barns, which constantly clean livestock barns and separate livestock excrement into excrement and waste fluid. , Recently, Special Publication No. 55-37214 is known.

This device has a movable frame that can be reciprocated over a manure receiving bed with a slit and a drainage pipe arranged in communication with each other at the bottom, and a connector is slidably fitted in the center of the movable frame. At the center of the moving frame and below the connector, the base of a feces removal plate for removing accumulated feces on the excrement receiving bed is pivotally attached, and the feces removal plate is movable up and down. Also,
The connecting tool is provided with a rod for pulling up the feces removal plate. When the movable frame returns, the feces removal board is lifted to the top of the excrement receiving bed by pushing the pulling guide provided on the feces removal board with a lifting rod, and when moving forward, it is lifted by its own weight. Then it comes into contact with the excrement receiving bed,
It is designed to remove accumulated feces on the feces receiving bed.

However, in the conventional device, when moving forward, that is, when the feces removal operation is performed, the feces removal plate slides against the excrement receiving bed using only its own weight, so if the load applied to the feces removal plate is small while it is moving, It is not uncommon for the excrement to climb over the feces on the excrement receiving bed, and it may not be possible to completely remove feces from the excrement receiving bed.
If feces were stuck between the feces removal plate and the moving frame, the sliding movement would be hindered, and feces could not be removed. Further, since the feces removal plate moves a considerable distance in the forward movement direction without slidingly contacting the excrement receiving bed, it may become impossible to perform feces removal work during that time. In addition, when feces is stuck on the excrement receiving bed, the feces cannot be scraped off, and this feces becomes an obstacle to the movement of the so-called scraper, which includes the feces removal plate and moving frame, and the movement of the device stops. There was also the problem of putting it away. Furthermore, since the feces removal plate is raised at a single point in the center of the moving frame, the feces removal plate may oscillate laterally.

``Object of the Invention'' Accordingly, the present invention enables the feces removal work to be carried out immediately after the feces removal without the feces board riding on the feces during the feces removal operation, and to remove strongly stuck feces on the feces receiving bed at any time. To provide an excrement separation and treatment device for a livestock barn, which can improve scraping and removal efficiency and further simplify the entire device.

``Summary of the Invention'' The present invention provides that during the feces removal operation, if the feces removal plate is simply brought into sliding contact with the feces and urine receiving bed using its own weight, it is not possible to scrape off the feces that are strongly stuck to the feces and urine receiving bed. Since this is possible, it was developed based on the idea that during this feces removal operation, the feces removal plate could be forcibly pressed against the excrement receiving bed to allow it to slide into contact with the excrement receiving bed.

That is, in the present invention, the sliding member is constituted by a sliding frame with a regulated amount of sliding back and forth, and the left and right side frames of this sliding frame have interlocking pins provided on both sides of the feces removal plate by sliding the sliding frame back and forth. An upright pin and a lodging pin are provided to raise and lower the feces removal plate by pressing, and the lodging pin forcibly presses the tip of the feces removal plate against the excrement receiving bed immediately after the movable body moves forward, and prevents this pressed state from moving forward. It is characterized by being maintained all the time.

“Embodiments of the invention” The invention will be explained below with reference to illustrated embodiments.

Reference numeral 11 denotes a concrete foundation wall, which is disposed in parallel in a semi-buried state in the ground of the livestock barn, with the wall surfaces facing each other. A slatted step board 12 is placed on this foundation wall 11, spanning both sides. Under the interior defined by the foundation wall 11, a long excrement receiving bed 13 is fixed with concrete.
This excreta receiving bed 13 has a slope that slopes downward from both left and right sides toward the center, and is designed to collect mainly waste water from livestock at the center. A slit 14 is formed in the center of the excrement receiving bed 13 along its longitudinal direction to serve as a drainage passage, and a cylindrical drainage pipe 15 is disposed under the slit 14 in communication. At one end of the excrement receiving bed 13 and the drain pipe 15, a receiving tank 16 for collecting excrement is installed.

A movable body 20 is slidably provided on the left and right side ends of the excrement receiving bed 13 via a sliding member 17 such as a sled. The sliding member 17 is integrally fixed to the lower end of the moving body 20. This moving body 20 has a pair of side plates 21 and 2.
2 are connected by a connecting frame 23 at their front and rear upper end positions, and integrally slide back and forth along the longitudinal direction of the excrement receiving bed 14. In addition, side plates 21 and 2
A support member 24 is provided near the center of the lower part of 2 so as to straddle both.

A slit scraping plate 25 is suspended and fixed at the center of the support member 24 at a position corresponding to the slit 14. This slit scraper plate 25 is loosely inserted into the slit 14 and has a lower end protruding into the drain pipe 15, and a disk-shaped urine collection plate 26 smaller than the inner diameter of the drain pipe 15 is attached to the protruding end. It is provided. This urine collecting plate 26 collects the drained liquid inside the drain pipe 15 while moving, and flushes it into the receiving tank 16 provided at the end thereof. Further, the support member 24 is provided with a plurality of hinge parts 27 along its longitudinal direction, and on this hinge part 27, a manure removal plate 28 that removes the accumulated feces on the manure receiving bed swings in the direction of the arrow. It is pivoted as possible. Therefore, the slit scraping plate 25, urine collecting plate 26, and excrement removing plate 28 integrally reciprocate in the left-right direction in FIGS. 2 and 3 as the movable body 20 slides back and forth. The fecal removal plate 28 has a hinge portion 27
The slope sloped downward from the top to the excrement receiving bed 13.
Excretion removing part 28a whose tip can come into sliding contact with the excrement receiving bed 13
A standing portion 28b stands up from the hinge portion 27 and extends upward, and an inclined portion 28c bends from the standing portion 28b and extends rearward at a slight upward slope.
It is equipped with The distal end of the excrement removal section 28a can be formed into a knife edge shape in order to enhance the excrement removal effect, and upright wall sections can also be provided on both sides thereof. A bar 29 is fixed to the rear surface of the upright portion 28b along the entire width thereof in the direction in which the hinge portion 27 is disposed. this bar 2
A pair of interlocking pins 30 are provided at the upper portions of both sides of the shaft 9, extending radially from the axis thereof. One of the interlocking pins 30 is used to pull up the excrement removal section 28a, and the other is used to push it down. Note that the inclined portion 28
c may not be provided.

A slide frame 32 is provided on the movable body 20 so as to be slidable in the front-rear direction, which is the sliding direction of the movable body 20. The slide frame 32 includes left and right side frames 33 and a front frame 34 and a rear frame 35 that connect the side frames 33 at the front and rear, respectively. The left and right side frames 33 are slidably supported by slide guides 37 and 38 fixed to the inner surfaces of the side plates 21 and 22. The amount of sliding of the left and right side frames 33 in the front-rear direction is determined by the stoppers 39, 4 protruding therefrom.
Regulated by 0. That is, the stopper 39
When the slide frame 32 comes into contact with the slide guide 37, the backward sliding of the slide frame 32 is restricted, and the stopper 4
0 comes into contact with the slide guide 38, forward sliding of the slide frame 32 is restricted. Front frame 3
Tow ropes 41 for pulling the slide frame 32 in the front and rear directions are connected to the centers of the slide frame 4 and the rear frame 35, respectively. This pulling rope 41 is connected to a winch (not shown) installed outside the end of the foundation wall 11 via a guide roller (also not shown).

In order to swing the excrement removal plate 28 about the hinge part 27, a pair of lifting/lowering linkages are provided at positions corresponding to the interlocking pins 30 at the lower central portions of the left and right side frames 33, which are opposed to each other with a bar 29 in between. A portion 42 is provided in a hanging projecting manner. When the side frame 33 slides, this raising/lowering interlocking part 42 engages with one of the interlocking pins 30 to swing the feces removal plate 28. When the side frame 33 slides backward, the lifting pin 30b is engaged with the lifting pin 30b. An upright pin 42 that presses to swing the excrement removing part 28a in the pulling direction.
b, and a lodging pin 42a that presses the push-down pin 30a when the side frame 33 slides forward, swings the excrement removing part 28a in the downward direction, and presses the tip against the excrement receiving bed 13.

Next, the operation of the excrement separation and treatment apparatus having the above configuration will be explained.

Now, with the excrement removal plate 28 in the imaginary line position shown in FIG.
When a tensile force is applied to the slide frame 32, the slide frame 32 is guided by the slide guide 37 and slides forward. Then, substantially at the same time as the engagement of the upright pin 42b with the pull-up pin 30b is released, the lodging pin 42a engages with the push-down pin 30a and presses the push-down pin 30a. As a result, the feces removal plate 28 swings in the downward direction about the hinge portion 27, and the feces removal portion 28a becomes inclined as shown by the solid line, and its tip is forcibly pressed onto the excrement receiving bed 13. At this time, the mobile object 2 is still
0 is not moving. Further, the stopper 40 is in contact with the slide guide 38, and the slide frame 32
is restricted from sliding forward. When the tow rope 41 is further pulled, the tensile force applied to the sliding frame 32, which is restricted from sliding, is applied to the moving body 2.
0, the moving body 20 now moves to the slide frame 3
2 and slide in the forward direction. Due to this sliding movement of the movable body 20, the fecal removal plate 28, the slit scraper plate 25, and the urine collection plate 26 move together in the same direction. At this time, the tip of the excrement removal part 28a, which slides forward while being forcibly pressed onto the excrement receiving bed 13 by the lodging pin 42a, easily removes excrement that is stuck on the excrement receiving bed 13 and is difficult to remove. Scrape it off and go. Therefore, the feces removal part 28a of the feces removal plate 28 is prevented from riding on the feces on the feces and urine receiving bed 13 that is caked on, and the feces and urine receiving bed 13 is clean without any remaining feces on the feces and urine receiving bed 13 during the movement. This aspect can be realized. Moreover, since the excrement removal plate 28 is already pressed onto the excrement receiving bed 13 immediately before the movable body 20 slides, there is no movement loss. Therefore, the feces removal work using the feces removal plate 28 can be started immediately after the moving body 20 slides. Furthermore, the situation where the movement of the feces removing plate 28 is obstructed by stuck feces is eliminated, and smooth movement during forward movement is ensured. Simultaneously with the movement of the excrement removal plate 28, the slit scraping plate 25 moves within the slit 14 to remove clogging of the slit 14, and the urine collection plate 26 sweeps away the drained liquid in the drain pipe 15. As a result, the surface of the excrement receiving bed 13 is cleanly removed, and the excrement is led to the receiving tank 16 along with the drained liquid.

From this state, when a tensile force is applied to the towing rope 41 in the backward movement direction (to the right in the figure), the slide frame 32 first slides backward, and the lodging pin 42
a releases the engagement with the push-down pin 30a,
At approximately the same time, the erecting pin 42b engages with the pulling pin 30b and presses the pulling pin 30b. As a result, the feces removal plate 28 swings in the upward direction and stops when the feces removal portion 28a is separated from the excrement receiving bed 13. In this state, the feces removal section 28
a is approximately parallel to the surface of the excrement receiving bed 13 with a considerable distance, and interference with newly deposited excrement is avoided. By this time, the stopper 39 is in contact with the slide guide 37, and therefore the rearward sliding of the movable body 20 is restricted. When the tow rope 41 is further pulled in the same direction, the movable body 20 returns integrally with the slide frame 32 due to the tensile force applied to the slide frame 32, which is restricted from sliding, as in the forward movement. slide in the direction of motion. With this, the excrement removal plate 28, the slit scraper plate 25, and the urine collection plate 26 also move in the same direction. At this time, the excrement removal section 28a is lifted above the excrement receiving bed 13, and therefore does not interfere with the excrement deposited on the excrement receiving bed 13.

In the above embodiment, the urine collection plate 26 is formed into a disk shape, but it can also be shaped to match the bottom shape of the drain pipe 15.

"Effects of the Invention" As explained above, according to the present invention, when the movable body moves forward, the manure removal plate is forcibly and strongly pressed against the excrement receiving bed by the lodging pin immediately before the movable body moves. Since it moves forward while maintaining this state while sliding on the excrement receiving bed, there is no loss of movement during the excrement removal operation, and there is no riding on the excrement during sliding, and it can also remove feces that are strongly stuck on the excrement receiving bed. Can be easily scraped off. Therefore, the feces and urine receiving bed is kept clean from top to bottom at all times, and smooth sitting of the device is ensured. Furthermore, when the movable body moves back, the feces removal plate is pulled up by the upright pin to a position where it does not interfere with the excrement receiving bed, so that the top of the excrement receiving bed is not soiled. Furthermore, since the lodging pin and the upright pin are provided on the left and right side frames of the slide frame, and these move the feces removal board from both sides, there is no horizontal movement of the dung removal board, and there are no obstacles in the storage section. Not only is the feces removal efficiency improved, but the structure is also simplified.
